Vinyl beginner frustrations Azimuth and VTA

Hi,

I've had my Pro-ject 6perspex turntable for a few weeks now, and its obvious now that there are several severe problems.

First of all, everything is placed slightly to the left. The soundstage is messed up, and too compact. When I move my head toward the left, vocals move left but stay in focus. When I move toward the right, vocals move right but immediately go out of focus and sound sort of like what you get when you mix up + and - on one speaker.

I guess this means that I need to adjust the azimuth. I've located the screw to do this, but I have no idea how much to move and how much movement is ok before I risk damage to the cartridge. The manual is a bit unclear on whether just twisting the screw is enough to adjust azimuth, or if I actually need to twist the tonearm manually. Could someone with the same turntable enlighten me? I'm also unsure about how the anti-skating weight might influence stereo imaging. There doesn't seem to be very much I can do with the anti-skating weight though, except selecting one of the three grooves.

Furthermore, while bass is tight and generally well defined (if a bit too overpowering on certain kinds of music), highs are virtually nonexistent, this is especially noticable for cymbals, which all but disappear. Midrange sounds more like what I get from cd, but especially vocals are too laid back and too far back in the soundstage

I searched around a bit, and from what I can see, the VTA needs adjustment. Again, I'm not sure exactly how much to move it by. According to this site http://www.walkeraudio.com/fine_tuning_your_turntable.htm I ought to raise the VTA.

However, my (horrible) pro-ject manual says the tube of the tonearm should be parallell to the record when it is lowered, but as far as I can see now it is slanting slightly downward, which would indicate that I should lower the VTA.

Hope I'm not too verbose... just needed to let off some steam :)
PS: I don't have any setup tools yet except the paper aligment tool that came with the table. I did order the one on www.turntablebasics.com though.
